Semen lini mucilage

On the middle curve are situated Na arabinate, Na pectinate, Na semen lini-mucilage and Na pectate all having carboxyl groups. They will be called carboxyl colloids. 

If the conclusion drawn is correct, a similar behaviour of other negative hydrophilic sols as to the influence of indifferent salts on the relative viscosity was to be expected. Indeed the electroviscous effect has been found to exist in all cases investigated, viz.t gtim arabic soluble starch mucilage of semen lini and of carrageen, sodium thymus nucleate and sodium yeast nucleate. Pecularities shown by some of these examples will be discussed later p. 223 10 and p. 227 11.
